Weibull Analysis of Right-Censored Data with a Free Software

Dear friends, we are happy to release our103rd technical video! In this video, Hemant Urdhwareshe explains and illustrates procedure to perform Weibull Analysis of right Censored data (or suspensions) using a free open-source software ‘Reliability Analytics Toolkit’. Hemant is a Fellow of ASQ and is certified by ASQ as CRE, Six Sigma Master Black Belt, CQE and CMQ/OE. This will help viewers to understand how to perform Weibull Analysis of incomplete right censored data without investing in expensive software.

The Curious Case of “Normal” Bearing Failure

When Poor Habits Become the Norm

Opening Scene

Imagine an intricate and lengthy production line, where every minute of inactivity costs thousands of dollars. The constant buzz of motors and conveyors conceals a profound tension: production goals are approaching, supervisors are vigilant, and the pressure remains unyielding.

In a constrained environment with a limited maintenance budget and sparse spare parts, your inexperienced and stretched-thin team constantly reacts to urgent breakdowns, prioritizing speed over thoroughness. Shortcuts become necessary for survival, leading to misaligned work and temporary fixes. While immediate repairs may succeed, small defects accumulate, resulting in entrenched bad habits and hidden failures. Eventually, a critical breakdown occurs, revealing the underlying issues, marking the start of a necessary investigation. [Read more…]

Systems Thinking Improves Reliability and Dependability (15 ways to do it)

Organizations can systematically enhance reliability and dependability by integrating key approaches into the development, deployment, and maintenance processes of their products and systems. Systems thinking rules! Despite subtle differences in terminology, regular assessments and updates should be conducted to address emerging challenges and technological advancements. This article provides a brief description and demonstration of several key approaches for enhancing reliability and dependability.

Reliability and Dependability Are Often Used Interchangeably

When it comes to choosing the right word to describe a product or service, the terms “reliability” and “dependability” are often used interchangeably. However, there are subtle differences between the two that can impact how they are perceived in practice and by consumers.

Reliability Allocation

In the realm of complex electromechanical systems, reliability allocation is a critical process that demands a delicate balance between safety, cost, and performance. As engineers, we are tasked with creating systems that not only meet functional requirements but also operate safely, efficiently, and cost-effectively over their intended lifespan. This article explores key strategies for optimal reliability allocation, emphasizing the importance of safety while considering economic factors and system performance.

5 Clues Using MTBF is Not Helping

Have you ever heard the claim that “We use MTBF, as it’s working just fine”?

They may be profitable and successful in the marketplace. Is MTBF serving them well?

Probably not.

One way help the folks claiming MTBF is alright is to illustrate using a better reliability metric may provide an improvement over using MTBF. Asking a few questions may find the inevitable chink in the MTBF armor.

Any early failures due to supplier or assembly error?
Any test design to check for how long the system will last?
Ever notice maintenance seems to improve or degrade system performance?
Did you fix the time frame for the calculation of MTBF?
Do you plot and track the month to month changes in MTBF?

The Ghost Company

All truth passes through three stages. First, it is ridiculed. Second, it is violently opposed. Third, it is accepted as being self-evident.

I’ve seen the Future Of Work. And, I don’t like it. Why? In Portland, Oregon, a retail store sells kombucha, a slightly alcoholic green or black tea. Great location. Great storefront. Sure money-maker!

Equipment Reliability 101

Learn Vital Equipment Reliability Basics for Equipment Reliability Management Success

Learning how to run your industrial plant and equipment to get outstanding reliability requires an understanding of its failure mechanisms.

You can have tremendous equipment reliability if you use the right maintenance strategies at the right times during the equipment life cycle to prevent the causes of failure.

Abstract:

Equipment Reliability Basics 101 for Reliability Management. When you understand the behaviour of equipment over its lifetime you will understand why proactive maintenance (as opposed to repairs) is critical. Our technologically based society depends on machinery and equipment to keep it operating. Knowing how equipment behaves during its operating life, and why it fails from time to time, means you can set up the right maintenance strategies to deliver lifetime reliability. Learn to apply the correct ways to use equipment failure curves to select your maintenance strategies. Change your maintenance and operating practices to control and eliminate failure and ensure you deliver outstanding equipment reliability.Keyword: Keywords: Equipment reliability management, reliability curves, equipment failure curves

The Best Definition of Reliability Centered Maintenance I Ever Heard

Storytime: What is Reliability Centered Maintenance (RCM)? This is the best definition of RCM I ever heard.

In this video, I share a story that has stuck with me throughout my 26-year journey with Reliability Centered Maintenance (RCM). It all started when I was working as a civilian employee at the US Navy’s Naval Warfare Center in Lakehurst, New Jersey. One evening, during a dinner with the British Royal Navy’s RCM team in Bath, England, Commander Andrew Matters shared a simple yet profound definition of RCM: “RCM is nothing more than common sense applied to physical assets.” That definition has guided my understanding of RCM ever since.

RCM might seem complex, but at its core, it’s grounded in practical, common-sense principles. In this video, I explain how RCM helps us identify safe and cost-effective maintenance tasks, manage failure modes, and build a strong reliability culture. When applied correctly, RCM has the power to transform organizations—and I’ve seen it happen firsthand.

What’s keeping you from carrying out a couple of RCM pilot projects? Why not see for yourself how RCM can make a difference for your equipment and your reliability team?

I’m Nancy Regan. Thank you for watching!
